Are they actually saying that you can have a list of keys ("qw(wins places shows losses)") and set the values by setting this to the list "@standings"?? Really?
Why not just try it and see?? A toy experimental program takes less than a minute to create and run. Really!
>perl -wMstrict -le
"use Data::Dump;
;;
my $self = { foo => 'bar' };
my @standings = qw(1 2 3 4);
;;
@$self{ qw(wins places shows losses) } = @standings;
;;
dd $self;
"
{ foo => "bar", losses => 4, places => 2, shows => 3, wins => 1 }
